x Mangave plant named ‘Red Wing’

ABSTRACT

A new and unique x Mangave plant named ‘Red Wing’ characterized by a large mound of broad, fleshy, mostly flat foliage with small flexible cream-colored marginal teeth that become firm and orargish-colored when mature. Foliage is upright to outwardly toward stem with a tendency to arch in maturity. The flowers are upright, a mixture of yellowish-chartreuse and reddish orange formed on stiff, branched stalks. The new plant is suitable for the garden or as a potted plant in the garden or home.

Botanical classification: x Mangave hybrid; Manfreda times Agave.

Variety denomination: ‘Red Wing’.

STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(B)(6)

The first public disclosure of the claimed plant, in the form of aphotograph and brief description on a website operated by WaltersGardens, Inc. on Feb. 1, 2018. The claimed plant was first sold on Feb.12, 2018 by Walters Gardens, Inc., who obtained the plant and allinformation relating thereto, from the inventor. No plants of x Mangave‘Red Wing’ have been sold in this country or anywhere in the world, norhas any disclosure of the new plant been made, more than one year priorto the filing date of this application, and such sale or disclosurewithin one year was either derived directly or indirectly from theinventor.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct x Mangave hybridplant, x Mangave ‘Red Wing’ that was hybridized by the inventor at awholesale perennial nursery in Zeeland, Mich., USA as a cross between anunnamed proprietary selection between Manfreda longiflora (not patented)as the female or seed parent times an unnamed selection of Agave shawii(not patented) as the male or pollen parent. The cross was performed onSep. 17, 2012 and seeds were harvested and sown in early 2013. Throughtrials at the same nursery the plant was assigned the breeder code12-71-2. The new plant has been successfully asexually propagated bysterile shoot-tip tissue culture and by basal offsets at the samenursery in Zeeland, Mich. The asexual propagation has been found toproduce stable and identical plants that maintain all the uniquecharacteristics of the original plant in multiple generations.

BRIEF SUMMARY OF THE INVENTION

x Mangave ‘Red Wing’ differs from its parents as well as all otherManfreda, Agave and x Mangave known to the applicant. The female parenthas foliage that is narrower, thinner in cross section, has smallermarginal teeth and has significant mahogany mottling or spotting on bothupper and lower surfaces. The flowers of the female parent are smaller,near white turning to reddish in maturity, with short stamens. The maleparent is more upright in habit, slower growing, with foliage that isshorter, more glaucous bluish-green without red, broader, more ovatewith larger marginal teeth and larger terminal spines. The nearestcomparison plants are ‘Mission to Mars’ U.S. Plant Pat. No. 29,393,‘Freckles and Speckles’ U.S. Plant Pat. No. 30,904 and ‘Purple PeopleEater’ U.S. Plant Pat. No. 29,949. ‘Mission to Mars’ has broader andlonger leaves and is larger in habit. ‘Freckles and Speckles’ hasfoliage that is longer and has less dense reddish coloration, and theplant matures to flowering faster with petals that are less orange hueand anthers that are more burgundy. ‘Purple People Eater’ has foliagethat is more upright and fleshy, of a greenish-purple withreddish-purple spots and less dense reddish coloration.

The new plant, ‘Red Wing’, is unique from all of the above cultivars andall Agave, x Mangave and Manfreda known to the inventor by the followingcombined traits:

-   -   1. Large mound of glaucous, densely maculate with reddish spots        to nearly solid reddish in high light;    -   2. Leaf margins have small, flexible, cream-colored marginal        teeth that become orangish and firm when mature;    -   3. Upright flowers on slightly ridged or fluted, upright,        branched stalk;    -   4. Flowers are mixtures of yellowish-chartreuse and reddish        orange;    -   5. Moderate to slow growth rate;    -   6. Foliage is upright to outwardly toward stem.

BRIEF DESCRIPTION OF THE DRAWING

The photograph of x Mangave ‘Red Wing’ demonstrates the overallappearance of the new plant including the unique traits as afive-year-old plant grown in a container in Zeeland, Mich. The colorsare as accurate as reasonably possible with color reproductions. Ambientlight spectrum, temperature, source and direction may cause theappearance of minor variation in color.
